. This invention relates to snow p1ows,-and particularly to the type .of snow plow adapted to be mounted on a vehicle and used for plowing roads, v. city streets, 'railroad -right-of-ways, etc.

It is an object of this invention vto provide an improved snow plow having therein a snow scoop, a rotary fan for discharging the snow, and means for conveying the snow from the scoo to the fan.

Another object of the invention is to pro- -vide a snow plow having a fan casing, a fan therein, and a spout adapted to be'both vertically and horizontally adjusted to direct. the discharge of snow vfrom the fan casing in various directions. u

It is still 'another object of the invention j to provide a snow plow scoop, a fan casing, a fanv within the casing, anda helical conveyor adapted to carry the snow from the scoop to the fan. casing.

It is yet another object to provide in a snow plow, having a scoop and conveyor, a

' snow disintegrating means adapted to break up the snow in advance of the conveyor, and directthe` same into the conveyor.

A further object is to provide a snow scoop having aachannehtherein adjacent its rear end, within 'which aconve or is adapted to operate, and a snow de ecting plate above the conveyor'.

These and other objects of the invention will more fully appear vfrom the following description made in connection with the accompanying drawings, in which like reference characters refer to the same parts throughout the several views, and in which, Fig. 1 is a vertical section taken on the line 1-1 of Fig. 2; and

Fig. 2 is a sectional plan view of the device taken on the line 2- -2 of Fig. 1.

Referrin to the drawings, a snow scoop 3 is provide extending upwardly and rear.

wardly from the forward portion of the machine. The lower edges of the scoop 3 are'secured to sideboards 4, the scoop Aer.- tending'transversely between the two sideboards. A prow 5 is fixed inthe central forward portion` of the scoop, dividing the scoop into two sections'v formin mold boards. Behind the prow 5, a cy indrical fan casing 6 is positioned, secured to the prow and to the Vcentral portion of the scoop. Angle bars 7 are secured at either side of the fan casing, 'and extend insulo-l stantially a horizontal plane to the rear of having a snow `the machine.f Angle 'bars 8 are *pivotally secured to the bars 7, respectively, by means tion fitted within the interior' threads of a hollow tube 13, pivoted in turn to la bracket 14 secured to bar 11. Rod 12 is adapted to be adjustably secured in tube 13, and held in lace by means of a lock nut 13a.

ecured to the bottom of the Esideboards 4 and to the side edges o the front portion of the scoop 3, are runners ,15 having the usual upti'rned lips at their forward ends and extending rearwardly therefrom, to be 'connected to the scoop, 3 ladjacent their rear ends by means of the braces 16. A central runner 17 is secured`below prow 5 and fan casing 6. The conveyor and fan shaft v18 is journaled in the sideboards 4 and runs transversely through the center of the cylindrical fan casino' 6, being additionally journaled adjacent t-Lhe fan casing in brackets 19 depending from the bars 7. Helical scoop conveyors 2O and 21 are secured to the shaft 18, one at either side of the fan casing- Conveyor 20 is of the left hand screw type, while conveyor 21 is of the right hand screw type. rhe fan casing 6 has central openings at either side adjacent the inner ends tively. A fan 22 is secured within the fan casing to theA shaft 18. Scoop ,3 has a curved channel portion 3a adapted to fit around the rear side of the two conveyors, and to form a. channel therefor within which the conveyors may operate. A projecting snow defiecting plate 3b. is formed at the upper-rear end of the scoop 3 and extends outwardly over the conveyors.-

The fan casing 6 is formed with a tangential discharge outlet' 6l having connected thereto'a tubular conduit or spout 23 having an adjustable elbow 23a therein. The lower section of said elbow tits within discharge outlet 6a and is rotatable therein. Secured to the lower-most section of the elbow 23 is a circular worm gear rack 24bearing 'against the top 'of discharge'outlet 6a and co-operating with the Worm 25 secured on stub shaft 26 journaled within 'bracket 2 7, which in turn is secured tothe top of the w a of the helical conveyors 20 and'2l respecfan casing 6. Shaft 26 has a squared head with which any common. type of crank 1s adaptedto co-operate for turning the worm 25 and thereby rotating theV spout 23.' A support for the spout 23 shown as a. rod 28 is secured to the elbow 23a and has an e e therein at its upper end through which the cable 29 extends. Cable 29 is secured at one end to a lug adjacent the outer end of`the spout 23 and extends rearwardly` to be operated by the operator of the vehicle to whichthe plow may be secured for vertlcal adjustment of the spout about the elbow 23a. Spout 23 has'any common type of ad- 'ustable hood as 41secured at its outer end. The hood 41. is shown as pivoted to the spout and is capable of angular adjustment in respect to the discharge end of the spout by means of a bolt 41a extending through the spout and y being adapted to extend through any one of a ser1es of spaced apertures in the hood.

Asnow disintegrator 1s mounted at the upper front portion of the plow and. comprises a transverse shaft 30 journaled inQthe sideboards 4 at their upper forward portions andy in the bracket 31 secured to the top of the prow 5, the radial arms 32 secured tov shaft 30 at spacedintervals thereon and the snow engagin blades 33 secured at the ends of arm` 32.' v haft 30 is mounted forward of and above shaft 18- j A main driveyshaft 34 is journaled in the rear ends of the sidebcards 4 and also in the `hinges 9 connectin the bars 7 with the bars j 8. The drive sha t 34 has sprocket wheels 35 secured thereto, one adjacent an end thereof and one adjacent each of the hinges 9 at the outer sides thereof. 'A sprocket wheel 36 is secured adjacent one end of the yconveyor andv fan shaft 18, and is adapted to be driven-from sprocket 35 adjacent the end of shaft 34 by means of an endless chain 37.

` ,wheel 35 a jacent one of the hinges Operation.

The snow plow having been secured to a vehiclepreferably at the front end thereof (not shown), and the drive chain 40 having been connected to a rotatable part of the vehicle, the device is ready for operation. Push rod 12 is first adjusted by means of lock nut 15 to set the plow at' the correct angle of adjustment with the/ground. As

the plow is pushed forward by the vehicleY and the drive shaft 34 is rotated, the shafts 18 and 30 will be rotated, thereby operating of the plow.

the helical conveyors' 20 and 21,\the fan 22 and the'disintegrator arms and blades 33 and 32. As snow is encountered by the forward end of the scoop, it will be elevated thereupon until forced into the helical conveyors 20 and 2l.. The rotatin conveyors will carrythe snow to the insi e of the fancas- ,ing 6 where the same will be projected outoutwardly from the spout 23 in any desired direction, by placing the spout in the prop erly adjusted position and by properly adjusting hood 41. Asthe outlet mouth of the spout may be raised to a considerable height and as fan 22 is adapted to be rotated at high velocity, it will be seen thatl snow may be discharged from said spout at a considerable distance from the plow. j

I f heavy drifts of snow yare encountered, or 1f it isfound that the snow will pile up 1n front of the helical conveyors 20 and 21, the radial arms 32 and blades 33 of the disin- -tegrator will break the snow up and'will directv the same into the helical conveyors. 1f it is found that snow will pile up over the top of the conveyors 20 and 2l, the snow deflecting plate 3b will direct the same downwardly against the conveyors and prevent the snow from being carried over the rear The runners 16 and 17 will permit the plow to be readily slid over -ice and snow if. the angle of deflection of the plow with the ground is such due to the adjustment of the push bar 12 that the runners -will touch Athe ground. The whole plow is adapted to be supported from the vehicle by means of the bars 8 and the hinge 9 when they push bar 12 is properly adjusted. The hinged connection between bars 7 and 8 permit the plow 'to be raised or lowered as .the push bar is adjusted to be raised entirely off the ground or to bear against the ground as may be desirable at various times.

lli

The device is simple 1n operation, comprises but comparatively few parts, and is very eilicient for ,the purposesv Iset forth. It is found that by use of the fan lin connection with the spout 23 that snow may be carried a. considerable distance over the side of the road plowed. VVith thei usual type of plow now employed, snow 'is merely pushed to one side of the road and thei same will for'm ledges at the side of the road,

causing huge drifts across the road when further snow falls. By use of the present Invention, the snow discharged by the spout 23 at some distance from the side of the road will form ledges of snow at these points which will act as snow fences to prevent the drifting of snow across the road when further snow falls. Spout 23 can be quickly raised or lowered or turned to direct snow in different directions. This feature is highly advantageous in that the spout may be turned to discharge snow at one side of the road rather than upon a cross road when a cross` road is approached, in operation of the device. The best effect may be had in using the plow in directing the discharge of snow in the direction towards which the wind is blowing.

The plow will be found highly useful in clearing city streets where the disposal of b the snow after being plowed from the center of the streets and the sidewalks is always a big problem. The device can be used on such streets and the snow directed by means of the adjustable spout and hood into a dump wagon or truck which may follow along beside the vehicle upon which the plow is mounted, when the device is in operation,

and the snow thus may be livered for nal disposal plowing operation.

It will, of course, be understood that various changes may be made in the form, details, arrangement and pro ortions of the parts, without departing rom the scope of applicants invention, which, generally stated, consists in a device such as 1s shown and described and set forth in the appended claims.
